The legs movment is pretty acurate, (I live in a desert too, so I know scorpions and tarantulas pretty well) the shadows are really nice, my only gripe is some of the enviroments, the human scenes are good, but the desert need some polish. Oh and one of the human characters is a really freaky dude.
